Hierarchical perception of melody
2009
Two experiments were designed to investigate the hierarchical perception of melodies. The hierarchical structure of tonal melodies is formally described in Lerdahl and Jackendoff's Generative Theory of Tonal Music (GTTM). The experiments were designed to assess different aspects of GTTM time span reduction quantitatively. Subjects were presented with pairs of melodies in a same-different task. A short novel and a longer original tonal melody could differ within the harmonic context at single tones on one of four time span reduction levels. It was found that detection rate of the melodic deviances correlated strongly with time span level. The same method was employed on an atonal and a poorl…
The Effect of Expertise in Evaluating Emotions in Music
2013
This study investigates the role of expertise in the listener judgment of emotion in music. Previous studies suggest that the most important factors are mode and tempo, respectively influencing valence and arousal. The effect is stronger when the two parameters converge (major mode combined with fast tempo and vice versa), whereas tempo predominates when they do not converge. An open question is whether and how these judgments vary with the expertise of the listener. Our hypothesis is that non-experts will base their evaluation mainly on tempo, disregarding mode, which is more complex to be aware of. On the other hand, experts will take advantage of both sources of information. The experime…
An integrative dual-route model of rhythm perception and production
2009
An integrative dual-route model of rhythm perception and production is proposed here. Furthermore, an empirical study illustrated in the second part of this paper provides evidence of the existence of two different cognitive pathways. The development of the model is based on fundamental psychological principles of perception, action control and relevant neurobiological findings in rhythm processing and sensorimotor synchronization. Experiments with a dual-task paradigm were used during synchronization tapping to verify the fundamental assumptions of the model. The aim was to examine whether professional drummers show a change in tapping performance when their attention is drawn to another t…
